by Ryan Kelly 16 Jan '09

Hi All, I'm pleased to announce the v0.3.0 release of filelike, a module for easy creation and manipulation of objects that provide a rich file-like interface. New in this version we have: * support for seek() and tell() in FileLikeBase * much better support for intermingling reads and writes * rearranged filelike.wrappers to provide consistent naming scheme * filelike.join function: concatenate several file-like objects so they behave like a single file * filelike.slice function: access a portion of a file-like object as if it were an independent file * Buffered wrapper class: emulate seekability on streaming input/output Along with a host of small fixes and new test cases. All the details are available at the project website: http://www.rfk.id.au/software/projects/filelike/ Cheers, Ryan -- Ryan Kelly http://www.rfk.id.au | This message is digitally signed.

Regular Toronto Python User's Group meeting: Using CouchDB from Python
by Mike C. Fletcher 14 Jan '09

14 Jan '09

This month we're going to have a presentation from Myles Braithwaite on how to use the CouchDB system from Python. According to Myles this is the stuff he couldn't get to when he presented the library at TLUG last month. CouchDB is an Erlang-coded distributed "document oriented" database with bi-directional replication mechanisms. There is a Python API and Myles will be discussing how you go about actually using CouchDB in your projects (hopefully he'll cover the "why you'd want to do that" stuff too :) ). We'll meet at Linux Caffe, at the corner of Harbord and Grace, one block South of Christie station, at 7:00pm. We'll start the formal presentation at 7:15. Directions are available on the website's next-meeting page: http://www.pygta.org Have fun all, Mike -- ________________________________________________ Mike C.

pyjamas 0.4p1 release
by Luke Kenneth Casson Leighton 14 Jan '09

14 Jan '09

This is a minor patch release of pyjamas 0.4p1, the Python-to-Javascript compiler and Python Web UI Widgets Toolkit. What is Pyjamas for? Pyjamas allows a developer to create U.I applications in python as if the Web Browser was a Desktop Widget Set toolkit platform (like pygtk2, pywxWidgets and pyqt4, only much simpler, and more powerful). No knowledge of javascript programming is required: the python-to-javascript compiler takes care of the conversion between python and javascript, and the U.I widget set takes care of all the browser and AJAX incompatibilities. Why don't I find that exciting? The significance of pyjamas takes a while to sink in. Or you're not a UI developer. Or you've never been asked to write an identical app that works on both the desktop and all major web browsers. If you're a python developer who has followed the history of web application development of the past decade, with much frustration and disappointment, is overwhelmed by Javascript, AJAX and the demands of the "Web 2.00o0ooo0 Revverlushun", then Pyjamas is something that you should consider investigating. Pyjamas 0.4p1 Bug-fixes (and accidental Features) Significant bugs fixed include HorizontalPanel's remove() function, SimplePanel's clear() function, and sprintf with multiple arguments ("%s %d" % ("hello", 2) will now work) Dialog Box now has modal functionality (thanks to jurgen kartnaller). HorizontalSplitPanel has been added, although both the horizontal and vertical panels operate correctly on Mozilla-based browsers, but Safari and IE need volunteers to work on them. Several more examples have also been added, including a spreadsheet-like GridEdit example; a Transparent SVG canvas clock widget (that actually tells the time); an "Information Hierarchy" example that could be used as the basis for an online cooperative spreadsheet editor; Erik Westra's "Showcase" source code which provides and shows the source of the 30 widgets being demo'd; and a few other minor examples.

*What's New in Python?* Stuck using a rusty ol' snake? All Pythonistas within striking distance of Maryland are invited to the *BACON-PIG* meeting on January 19th to learn about all the new features in Python since 2.4, with an emphasis on Python 2.6 and 3.0. Barry Warsaw, Release Manager for Python 2.6/3.0, will present the latest stuff, along with some insights on porting existing code. We have a full 2 hours reserved for the meeting, so there will be lots of time for questions and discussion, after which we'll adjourn for the customary post-meeting sushi outing and pythonistic schmoozing! Here are the meeting coordinates: Space: NASA/Goddard Visitor Center <http://www.nasa.gov/centers/goddard/visitor/home/index.html> Time: January 19, 2009, 5:30 - 7:30 PM BACON-PIG resources: site: <http://pangalactic.us/bacon-pig/> list: <https://pangalactic.us/mailman/listinfo/bacon-pig> Cheers, Steve Waterbury -- "I put a dollar in one of those change machines.

Dear Python users, After a quite silent month (during which we did not remain completely inactive), the Elisa team is happy to announce the release of Elisa Media Center 0.5.23, code-named "Play The Game". Elisa is a cross-platform and open-source Media Center written in Python. It uses GStreamer [1] for media playback and pigment [2] to create an appealing and intuitive user interface. The main highlight of this release feature-wise is on the plugins installation: plugin updates will now be silently installed by default as well as new recommended plugins. New configuration options allow to tune this default behaviour. On windows, Elisa is now able to restart by itself after installing plugin updates.
